A 50-G Cube of Ice,initially at 0 $\degree$ C,is Dropped into 200 G of Water in an 80-G

A 50-g cube of ice,initially at 0.0 $\degree$ C,is dropped into 200 g of water in an 80-g aluminum container,both initially at 30 $\degree$ C.What is the final equilibrium temperature? (Specific heat for aluminum is 900 J/kg* $\degree$ C,the specific heat of water is 4 186 J/kg*(\degree\) C,and L_f = 3.33 ´ 10⁵ J/kg. )

A) 17.9 $\degree$ C
B) 9.5 $\degree$ C
C) 12.1 $\degree$ C
D) 20.6 $\degree$ C
